To all 'whom 'it may concem:

Be it known thatLHAnmroN F. Low, a citizen of the United States,residing at the borough of Manhattan, city, county,and State of NewYork, have invented new and useful Improvements 'in Dish-WashingApparatus, 'of which the following is a specification. This inventionrelates todish washing apparatus, and has for its object to provideimproved apparatus of this character which will be superior in point ofeciency, durability andeconomy, and safety in operation.

The invention has for its particular object the provision of apparatusof the character described, whereby the cleansing water may be caused toexecute a highly eiicient to and fro movement above and throughoutl thepile or load of dishes to be washed, at the same time in Lthe main beingdirected downwardly upon the ,dishes so as to prevent disarrangement ofthe same, with the attendant breakage or fracture,` during the washingoperation.

In the drawings: Figure l is a front elevation of a dish washingapparatus constructed according to the invention; Fig. 2 is an enlargedvertical transverse sectional View of tank 1, taken upon the line a-a,Fig.v 1, and looking in the direction of the appended arrow; Fig. 3 is.a substantially horizontal transverse sectional view of the same, takenupon the lines b-b, Fig. 2, looking in the direction of the appendedarrow; and, Fig. 4 is a per- O spective view of a diffusion elementconstituting an essential part of the invention. vCorresponding parts inall the figures are denoted by the same reference characters.Referring'with particularity to the drawings, thevinvention isillustrated aslbeing comprised within two as sembled casings or tanks, 1and 2, used respectively for washing and rinsing. While Ibut one of theWashing tanks 1 is shown, a number ofthe same may be employed, saidtanks being arranged in a battery, and being duplicates in formation andprovision of operative parts, and being used', in practice, for theinitial washing operation. Without reference to the number of the :tanks1, but one of the rinsing tanks 2 is required for the 4final rinsingoperation.

Each of the tanks, 1 and-2, is provided at its lower forward portionwith an inlet header 3, and connected with both of said headers is asteam supply pipe, 4 and a water supply pipe 5, cocks 6 and7respectively being installed between the steam supply pipe 4 and theheaders 3 and between the water supply pipe 5 and the headers 3.

` Each of the tanks 1 and Z is provided at its upper forward portionwith an overflow header 8, which headers are connected by an overflowpipe 9, which is extended downwardly, as at 10, and horizontally beneaththe tanks, to form a discharge pipell, communicating with dischargelpipes 12, one of which connects with the bottom portion of each of thetanks.

pipes 12 is controlled, in its communication -with the The bottom ofeach of the tanks with a bottom 14 which includes a screened orifice 15communicating with the respective discharge pipe 12. Each ofthe tanks 1and 2 is preferably four-sided, .and

each of the corners of the same, at the bottom of then tank, isseparately clit on by two upright partitions 16 which approach .eachotherinwardly atan acute angle and are but slightly spacedapart at theiradjacent outer edges. Each/couple of these partitions 16 forms, intherespective corner 16, a pocket into which the water in land 2 isprovided.

the tank flows in its circulation-through the tank. I testing upon theseveral pairs of partitions'l, is a grating or perforated detachablepartition 17 which extends across the tank but slightly-above tho bottom'14 thereof, the v grating 17 being also provided with or superposedupon an annular plate 18 directly beneath which, and above V the bottom14, is arranged an'agitator 19, comprisinga plurality ofcurved'bladesiixed to an upright shaft 20 journaled yin a"bearing 21fixed to the bottom 14, said vided with a pulley 22 whereby' it may beoperated. The agitator 19 operates in an agitation chamber between'thegrating 17 and base 14, and said agitatoris s o formed in theproportioning of its plates, as to draw the water downward through thegrating 17 from the interior of the tank. l y

At each of its four sides, each tank is provided with a ixedordetachable diffusion element y23', which said element consists of anupright plate 24 ranging downwardly Y within the tank slightlydivergently from the respective side thereof, from a point just beneaththe plane 'of the overflow header 8 tothe plane of the cornerpartitions' 16.` Each of these plates 24 is provided with side members25 which closely engage with the respective sides of the tank, and eachof said plates is preferably e detachably connected with the respectiveside of the tank, at its upper portion, by means of a screw or bolt 26.

Ashaft projecting beneath the bottom 14 and being pro- Each 0f theplates 24 is provided with two or more transverse seri'es of elongatedopenings 27, the openings of eachseries-being preferably arranged inaslight curvature, and above each series of openings is arranged atransverse baffle 28 extending between the side members 25. The baiie's28, when the diffusionelements- 23 are in place, extend obliquelydownwardly towards the sides of 'the tanks, and theopenings 27 areformed with substantially the samel oblique downward range.

4The operation, `method of use and advantages lof the improved washingmachine embodying the invention will be readily understood from theforegoing description taken in connection lwith the accompanying drawjing and the following statement.

When steam and water are simultaneously admittedto the headers 3, andfrom these headers the steam and water iiows into the tanks, and behindtwo of the diffu- L ings and downwardly onto the dishes.

- agitation is instituted within the tank, when the ow of materialsticking thereto; The overflow pipe 9 and disthe water within the tanks.It will be understood that sion elements 23'in the tank or tanks1,whence the hea-ted water is directed by the bafHes'ZS and through theopenings 27 downwardly upon theI dishes which are placed upon thegrating 17. At the same time, if the shaft 20 vis operated by the pulley22, the agitator 19- draws the water downwardly through the severalopenings 27 'from the spaces behind the several diffusion elements 23,the water passing inwardly through said op eni The water is also forcedinto the pockets in the corners of the tanks whence it issues throughthe spaces between the partitions and joins in the general condition ofagitation of the operation in each of the washing tanks employed is thesame. -lt results from the peculiar arrangement of the diffusionelements 23, the inlet of the first water into the tank behind one ofthe diffusion elements 2 3, and the combination of such diffusionelements with the agitator 19 and the partitions 16 in part or in wholefrom suoli arrangement and combination, that a condition of water andagitation of the same is set uup, which is accomplished by an ebullitionof the waterwithn the tank in a general downward and upward as well ascrisscross or to and iro movement. The downward movement of the wgaterkeeps the dishes firmly lseated upon the grating 17, and the to and froor crisscrossmovement of the water effectually dislodges from the dishesany charge pipe 11, through the headers Sand discharge pipes l2,permitof effectually draining the tanks and preventing overflow of thesame.

The entire apparatus is very positive and eflicient in operation andcomparatively simple and inexpensive in construction, in View ofitseiiiciency; and its particular point of advantage consists of the highlyefficient results in operation obtained from the peculiar'arrangementand combination of parts and members causing the downward and upward andcrisscros's circulation of the cleansing currents'. n Y

I do not desire to be understood'as limiting myself to the particularconstruction of parts and members as de- A scribed and illustrated,butjreserve the right to vary the same, in adopting' the improvements tocondielements and an agitator located in the bottom of the cusingindependent of the diffusion elements.
